Carbon Capture & Storage (CCS

Climate Technology & Industrial Decarbonization: CCS Economics

Carbon Capture, Utilization and Storage (CCUS) is essential for decarbonizing heavy industrial point sources (cement, steel, chemicals) where chemical process emissions cannot be eliminated by electrification alone:

• The Concentration Effect: The cost of carbon capture is inversely proportional to flue gas CO_2 partial pressure:

• Bio-Ethanol Fermentation): Requires only dehydration and compression.

• Cement & Steel (15%–25% CO_2): Moderate cost.

• Natural Gas Power (4%–8% CO_2): High energy penalty.

• Direct Air Capture (0.042% CO_2): Extreme thermodynamic minimum work.

• The Amine Reboiler Energy Penalty: Liquid chemical absorption requires ~2.5 to 3.5 GJ of thermal steam energy per ton of CO_2 to break carbamate chemical bonds and regenerate the solvent.

• US Inflation Reduction Act Section 45Q: Provides a 12-year direct-pay tax credit of 85 per metric ton for permanent geologic storage and 60 per ton for enhanced oil recovery (EOR) / utilization.

How to Use This Calculator

Enter your Industrial Point-Source Facility Category — choose from Cement & Lime Kiln (15%–25% CO₂ concentration | ~85/t full-chain), Bio-Ethanol Fermentation (95%+ Pure CO₂ stream | ~35/t full-chain), Coal / Natural Gas Power Plant (4%–12% CO₂ post-combustion | ~75/t), Annual Uncontrolled Flue Gas CO₂ Emissions (Metric Tons / yr) (e.g. 1,000,000 (1.0 Million Metric Tons CO₂/year)), Target CO₂ Capture Separation Efficiency (%) (e.g. 90 (90% standard amine capture rate)), Amine Capture OPEX & Solvent Reboiler Heat ( / Ton CO₂) (e.g. 48 (48/ton steam regeneration & electricity)), Capture Facility CAPEX Amortization ( / Ton CO₂) (e.g. 22 (22/ton absorber columns & compressor CAPEX)), Supercritical CO₂ Pipeline Transport ( / Ton CO₂) (e.g. 8 (8/ton 50–100 mile pipeline transmission)), Deep Saline Aquifer Geologic Sequestration ( / Ton CO₂) (e.g. 9 (9/ton Class VI well injection & monitoring)), and IRA Section 45Q Carbon Sequestration Credit ( / Ton CO₂) (e.g. 85 (85/ton point-source permanent geologic storage)).

The Formula

IPCC \& IEA Levelized Cost of Carbon Capture and Storage (LCOCCS) equations:

Annual Captured CO_2 (Tons) = Total Uncontrolled Emissions × Capture Efficiency (\%)

Gross LCOCCS (\/Ton) = Capture OPEX + Capture CAPEX + Pipeline Transport + Geologic Storage

Net Cost per Ton = Gross LCOCCS - IRA Section 45Q Tax Credit (\/Ton)

Total Gross Annual Spend = Annual Captured Tons × Gross LCOCCS

Annual 45Q Tax Credit Value = Annual Captured Tons × 45Q Credit Value

Net Annual Cash Flow = Annual 45Q Value - Total Gross Annual Spend

Worked Example

For example, capturing 90.0\% of emissions from a cement plant producing with and \ under the Gross LCOCCS is \. Gross annual spend is \78.30 Million/year, offset by \76.50 Million/year in 45Q tax credits, achieving permanent deep subterranean geologic sequestration at a Net Cost of \ net operating deficit).

Understanding Your Result

For financial decisions, validate your result against your specific tax situation, current interest rate environment, and applicable regulations — these change frequently and vary by jurisdiction. A calculated estimate is a useful starting point; for decisions involving significant capital (more than one month's income), consult a certified financial planner (CFP) or CPA. Financial projections beyond 3–5 years carry increasing uncertainty — model a conservative, base, and optimistic scenario to understand the range of outcomes.
